(1) These soils are moderately deep to deep, well-drained loam or silt loam surface soils with loam or silty clay loam subsoils, formed primarily in sandstone residuum .(2) But figuring out exactly how to regenerate ammonia borane from the residuum left after hydrogen has been extracted remains a stumbling block.(3) After evaluation of the residuum and comparison with a threshold value, a fault signal is generated when the residuum reaches the threshold value.(4) The barite ore is massive and occurs within residuum derived from carbonate units.(5) the urban residuum(6) Type I peridotites are interpreted to be the residua remaining after extraction of a partial melt.
